g0704 conversion help

Post by Gra2472 »

Hello all

I started building a grizzly g0704 cnc conversion about 4 years ago. I managed to complete 90% of the conversion and have gotten to the point that I can control the x, y, and z axis, but I do not know how to connect to the spindle motor. I could use some help.
I have a UCONTRO Mach3 USB 3 Axis CNC Motion Control Card. It has a spindle control function but for the life of me I am at a loss as to how to wire it up to the machine. How in the world does this work?

Thanks
